To all whom it may concern:

Be it known that I, JOHN F. Fnoamr, of.

Rochester, in the county of Monroe and State ofNew York, have invented a new and useful Motor-Vehicle, fully set forth in the following specification and shown in the accompanying drawings.

The present invention relates to motor vehicles and more particularly to the typev employing swinging hollow spindles on which the wheels turn, the driving mechanism for the wheel being extended through the spindles to connect with the wheels, an

I illustrated structure; Fig. 2 is a section on the line a-a, Fig. 1; and Fig. 3 is a section on the line b-b, Fig. 1.

Referring more particularly to the drawings, 1 indicates the stationary axle casing of a front or rear axle of an automobile, this casing, in the present instance, being formed in two parts, secured together by bolts 2 and inclosing a differential gearing 3v which connects with the two sections of a shafting or turning axle 1 .also mounted within the stationary axle casing 1. The outer end of each section of the axle casing is preferably provided with a spherical enlargement 5, which is cut off at 6 at the extreme endof the housing 1. For engagement with each of said spherical enlargements 5, there is provided a hollow spindle 7, said spindle having preferably a spherical socket portion 8 formed of two parts connected by bolts 9, This spherical socket portion 8 is mounted to turn on the spherical portion 5 about a vertical axis, this being effected by two sepr ate pivot pins 10 and .terposed bearings 13, the wheel being confined on the spindle between an annular flange 14: on the spindle, and a nut 15'engaging external threads on the extreme outer end of the spindle.

Secured to the inner face of the wheel, is a ring or annular member 17 having a lateral flange 18-forming a braking member, while securedto the outer face of the wheel 12, is a disk 19, bolts 20 extending through the wheel'and serving as a common securing means for the ring 17 and the disk19.

The disk or hub plate 19 may have a central pocket into which one end of a stub shaft 21 projects, the stub shaft being connected to the disk by a key 22 which permits the .disk to be removed from the stub shaft 21 but serves as a means for communicating motion from the stub shaft 21 to the wheel 12. A knuckle or universal joint 23 connects the stub shaft 21 with the shaft l and is located in line with the turning axis of the hollow spindle 7 so thatfthe spindle and the, stub shaft 21 may swing together, bearings 121 being interposed between the spindie and the stub shaft. v

The braking appliances for the wheel embody preferably an internal annular braking sin-face 24 formed on the inner faceof the flange 18 and turning with the wheel 12;".

surface, braking members are provided pref-1 erably in the form'of two curved or segmental braking members 25 mounted on a common pivot 26' which extends from the inner face of an annular flange 27 surrounding the spherical socket portion 8,said flange fitting within the flangelS and providing a substantially closed chamber for inclosing the braking members 25. It is preferred to. make the pivot 26 integral with a pin or bolt 28, which extends through a tubular portion 29 on the spherical socket portion 8 and also through the pivot pin 10, so that a single fastener is employed for anchoring the pivot pin 10 and supporting the braking members 25. The braking members 25 are preferably moved away from braking position by a spring 30 which connects the braking members above the spherical side portion.

For operating the braking members. there may be provided an elongated bod 31 mounted betwe n the ends of the braking members 25 and rotatable to turn the brak- 21nd l1 ngz 3.131100 z (111;) 19 cpmdie T.
